How to Select a Silane Coupling Agent

 

There is no doubt that it is important to choose the right silane coupling agents for different substrates or the processing material. If you are looking for a silane coupling agent for surface modification, namely, to change the surface properties of the materials, you need to take the following factors or elements into consideration while selecting: 1) the kind of the surface hydroxyl groups; 2) the concentration of the surface hydroxyl groups; 3) the hydrolytic stability of the bond that has formed; 4)the dimensions of the materail base.

 

The bonding strength of different materials will be subject to the influence of such factors as the degree of wetness , energy of the surface, interlayer and polar adsorption and acid-base interaction. Therefore, it is also necessary to consider the composition of materials and their sensitivity to silane coupling agent reaction.

FAQS ABOUT SILANE COUPLING AGENTS

 

Q

What do silane coupling agents do？

A

A silane coupling agent is playing a role of bonding agent or bridging agent. It is used for the better adhesion effect between two different materials. Silane coupling agent is basically suitable for surface modification of all organic and inorganic materials.

 

Q

Are silane coupling agents hazardous?

A

Generally speaking, the unhydrolyzed silanes are not flammable and explosive, because the flash point is about 100 degrees. However, after hydrolysis, many silanes need to be hydrolyzed by adding VOC, so the flash point decreases to 50 degrees, which might be flammable.

 

Q

What is the function mechanism of the silane coupling agent?

A

The siloxy group is reactive to inorganic compounds, and the organic functional group is reactive or compatible to organic compounds. When a silane coupling agent is used between the inorganic and organic interfaces, a bonding layer of organic matrix, silane coupling agent and inorganic matrix is formed. It is called the silica layer which enables the chemical reaction of silane coupling agent to form a durable bond with non-silica-based materials.
